Add a few variant datasets/tracks to JB2 manually

-- Add a few variant data: Add manually the genotyping dataset tracks to JB2 config since Connor's script can't pick it up.

OK, I've added the three existing diversity sets for hypogaea:

• aradu1_araip1.gnm1.div.Clevenger_Korani_2018: Genotyping of African germplasm collection
• aradu1_araip1.gnm1.div.Otyama_Kulkarni_2020: Diversity data for the U.S. peanut core collection, genotyped relative to the diploid A. duranensis and A. ipaensis genome assemblies.
• aradu1_araip1.gnm1.div.Otyama_Wilkey_2019: Genotype data for US Peanut Mini Core collection.

to the jbrowse2 config for both the aradu.gnm1 and araip.gnm1 against which the variants in those files are located. As is typical, I also discovered that the compression for these genomes/annotations was not bgzip, so have fixed those. In case we ever need to recreate these following an autogenerate of the config by Connor's scripts, the commands I used to add these tracks to the configs are in my home dir on the dev-pb-jekyll VM: ~adf/jbrowse2_config_cmds
